  Purpose

Background:

- Deficiency of the IL-1 receptor antagonist (DIRA) is a condition that causes repeated episodes of inflammation. People with DIRA can have rashes, fever, and joint pain. Most treatments for DIRA are intended to control the immune system to stop these inflammations. There are drugs that can treat DIRA, but they have to be given daily as injections. Researchers want to try another drug, rilonacept, as a treatment for DIRA. It needs to be given only once a week. Rilonacept will be given to individuals who are at least 3 months old and who have DIRA.

Objectives:

- To test the safety and effectiveness of rilonacept for children and adults with DIRA.

Eligibility:

- Individuals at least 3 months old who have DIRA.

Design:

  • Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. Other tests to study pain and movement will be given. Imaging studies such as bone density scans and x-rays may also be taken.
  • Participants will have a minimum of four to five study visits over 12 months. Those who are on different anti-inflammatory drugs (such as anakinra) will stop taking them before beginning the study visits.
  • Participants will have rilonacept injections weekly while on this study. The dose will be adjusted as needed to help treat the DIRA symptoms. Participants will keep a diary to monitor their symptoms and any side effects.
  • Treatment with rilonacept will be given for 1 year. Participants will have study visits to monitor the treatment. They will provide blood samples and have other tests at these study visits.

Detailed Description:

Autoinflammatory diseases are illnesses characterized by episodes of inflammation that, unlike autoimmune disorders, lack the production of high titer autoantibodies or antigen-specific T cells. There is growing genetic and clinical evidence that specific cytokine pathways are dysregulated. Monogenic defects in the IL-1 pathway cause cryopyrin associated periodic syndromes (CAPS) and deficiency of the IL-1 receptor antagonist (DIRA), the latter is caused by mutations affecting the IL-1-receptor antagonist gene (IL1RN). Both disorders respond with complete resolution of the inflammatory response to treatment with the short acting IL-1 blocking agent anakinra. This exploratory study aims to examine the utility of the long acting IL-1 inhibitor rilonacept (rilonacept; Regeneron Pharmaceuticals, Inc.)

This pilot study is designed to address: 1) the utility and dosage of rilonacept needed to achieve inflammatory remission in children with DIRA who have shown a response to treatment with anakinra [Kineret[registered]]; and 2) to evaluate the safety and pharmacokinetics in young children on rilonacept.

Rilonacept is a recombinant fusion protein with picomolar affinity for IL-1 and a half-life of approximately 7.5 days in humans. It is approved by the Food and Drug Administration (FDA) for the treatment of adults and children 12 years of age and older with Cryopyrin-Associated Periodic Syndromes (CAPS), and was tested in the clinically milder forms of CAPS including Familial Cold Autoinflammatory Syndrome (FCAS) and Muckle-Wells Syndrome (MWS).

In this study, clinical, and laboratory parameters will initially be measured at baseline following a withdrawal of anakinra for 24 hours. Subjects will receive a course of therapy with rilonacept that is predicted to induce inflammatory remission. Clinical and laboratory measures of inflammation will be assessed; rilonacept dose escalation will be implemented as necessary to achieve clinical and laboratory remission. Subjects will remain on study for 12 months and primary end point will be evaluated at 6 months.

Those subjects who complete the 1-year treatment period and maintain improved clinical and laboratory parameters compared to baseline values, may continue to receive study medication at their current dose. Principal investigator will help to obtain insurance coverage for rilonacept for their continued treatment, and will discuss with Regeneron Pharmaceuticals, Inc. for additional supplies of rilonacept for these subjects.

  Eligibility

Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria
  • INCLUSION CRITERIA

    1. Male or female pediatric and adult subjects with mutation positive IL1RN indicating DIRA. For the first five patients enrolled, they must have been on a stable dose of anakinra during the 2-week period prior to screening visit. If the subject is on other medications such as NSAIDs, methotrexate and/or oral steroids, it is a requirement that these doses have been stable during the 2-week period prior to screening visit.
    2. Subjects greater or equal to 3 months of age (however the first 5 patients enrolled will be over 2 years of age). Subjects 3 months old or older will be enrolled after SMC data review of the first 5 enrolled patients.
    3. Participation in NIH study #03-AR-0173 ( Studies of the Natural History, Pathogenesis and Outcome of Autoinflammatory Diseases (NOMID/CAPS, DIRA, CRMO, Still s Disease, Behcet s Disease, and other Undifferentiated Autoinflammatory Diseases )
    4. Subjects currently treated with anakinra may be enrolled in this study even though their DIRA may be quiescent. For these subjects, a history of active DIRA prior to treatment with anakinra will be sufficient. Subjects will not take anakinra 24 hours before initiation of drug treatment. Treatment naive patients will also be enrolled after SMC data review of the first 5 enrolled patients.
    5. Females of childbearing potential (young women who have had at least one menstrual period regardless of age) must have a negative serum pregnancy test at screening and a urine pregnancy test prior to administration of study medication.
    6. Females of childbearing age and men able to father a child and who are sexually active, who agree to use two forms of effective birth control, including abstinence.
    7. Negative Purified Protein Derivative (PPD) test using 5 T.U. intradermal testing or the QuantiFERON(SqrRoot) - TB Gold test per the Centers for Disease Control and Prevention (CDC) guidelines, and no evidence of active tuberculosis (TB) on chest X-ray.

      Subjects with latent TB (positive PPD or QuantiFERON - TB Gold test) currently treated with adequate therapy for at least one month prior to first dose of study medication may be included. Full prophylaxis regimens will be continued while on the study.

      Subjects who have had active TB in the past with documentation of adequate treatment may be included with strict clinical and radiological follow-up as per current guidelines.

      The Infectious diseases service will be consulted regarding all patients with evidence of TB infection (latent or active, current or history) prior to enrollment, and as appropriate during the study.

      Subjects who have been BCG-vaccinated will also be tested. Interpretation of PPD and QuantiFERON - TB Gold test in BCG recipients will be the same as for subjects who have not received BCG vaccine.

      Guardian/parent able to understand, and complete study-related questionnaires.

      Guardian/parent able and willing to give informed consent and abide with the study procedures.

      EXCLUSION CRITERIA
